Kinds of Control Algorithms
• Master/Slave a single controller making
all the control decisions Single point of failure Difficult to expand Costly to install – more
wiring needed to connect sensors and actuators
Proprietary programming Proprietary solutions

Kinds of Control Algorithms
• Peer-to-Peer Distributed control
intelligence No single point of failure Easy to expand and add more
devices Less costly wiring installation
No home I/O wiring runs

Open and Independent
• Robust, reliable, proven device networking protocol on a chip
• Manufacturers of smart devices can get to market quickly
• End users no longer locked into single supplier
• Integrators can choose best of breed devices
• LonTalk is media independent • LonWorks tools operate on multiple
platforms • Multi-industry standards group ensure
interoperability
![Page 16: Lonworks Applied To Textile Dyeing](https://reader035.fdocuments.us/reader035/viewer/2022081512/554cb1dfb4c905335b8b4c41/html5/thumbnails/16.jpg)
Look for the LONMARK Label300+ members from 17+ countries ensuring plug-and-play operation
• Non-profit industry association Includes manufactures, integrators,
application developers, and end-users
• Establishes technical guidelines Industry specific task groups
• Promotes the LONMARK standard and certifies product conformance
• Provides a resource of device information • Governed by board of directors made up of
industry members Includes sponsor members and elected
representatives All members have a vote

Networking Technology
• Allows integration of device information across network of any size including the internet
• Requires the assignment of a logical identity for each device called the Domain/subnet/node address Assigned by the network
management tool
• Allows message packets to be isolated or forwarded by intelligent LonWorks routers

Network Variables
• The dynamic data sent or received by network devices
• Signal-type independent – temperature, pressure, volume, flow, etc.
• SNVT’s are standard network variable types as defined by the LonMark organization Known and documented structure,
size, range, etc.
• UNVT’s are manufacturer defined Tools may require resource files to
document data format

LNS is LonWorks Network Services
• Network management platform• Foundation for open &
interoperable networks• Provides a core set of
management tools and connectivity options
• Client/Server architectures• Supports configuration tools
from multiple vendors• Provides access to any point
of network information from any point on the planet

LonWorks is about Distributed Control Intelligence
• Many small devices – sensors, actuators, controllers Each containing a microprocessor that
implements the LonTalk protocol
• Each device subdivides control functionality into objects called functional blocks Could be I/O, controller, or system wide
functions
• Each device sends/receives small message packets that contain control data
• Can create large, powerful, and flexible networks across LAN’s and WAN’s

LonWorks Network Program
• The network image is a collection of configured devices and their associated connections (aka network variable bindings)
• A network management tool is required to configure device behavior and to define the network variable connections When the tool is finished it can go
away!
• LonWorks uses an event driven control process

Bus Topology
• A physical routing of the communication channel that includes a distinct beginning and end
• Must be doubly terminated at beginning and end
• Device to device wiring or short stubs
• Easiest to troubleshoot• Difficult to expand when you
need to add more devices

Free Topologies
• A flexible wiring structure of the communication channel that includes a ring, star, loop, or combination
• Can have long stubs to devices and tools, tap in anywhere on the channel
• Difficult to troubleshoot• Easy to expand• Easy to exceed media limits• Requires one terminator installed
anywhere on the channel segment

Backbone Topology
• Connects routers to a common backbone channel
• Typically installed in a bus topology and includes mostly routers, network tools, and systemwide control devices
• Can be high speed twisted pair – XF1250
• Can be high speed IP channel
